Newport drug dealer sentenced to life imprisonment for murder

A man who was dealing drugs on the streets of Newport has been sentenced for murder after he stabbed another man in the chest.

David Sisman, 21, admitted in Court that he was dealing drugs on 14 May 2024 in the Maindee area when he was approached by Lee Crewe.

Sisman produced a knife and stabbed the victim once to the chest which proved fatal.

During the trial, Sisman claimed he was acting in self-defence but the jury rejected his claim and found him guilty of murder.

David Roberts of the CPS said: “Sisman was dealing drugs on the street in broad daylight and made the decision to arm himself with a knife.

“The CPS had to prove that Sisman was not acting in lawful self-defence and the evidence put before the jury led to them convicting him of murder.

“This case is another tragic reminder of how dangerous carrying knives in public can be.

“The family and friends of Lee Crewe have suffered a terrible loss and our thoughts will remain with them.”

David Sisman was sentenced at Newport Crown Court on 28 November 2024 to life imprisonment and was ordered to serve a minimum of 24 years.
